Prior to version 3.14.0, cookies set with the `cookies` parameter on requests are sent after following a cross-origin redirect. If a developer uses the `cookies` parameter on a per-request basis then sensitive data might be leaked to an attacker if they manage to control a redirect. Version 3.14.0 patches the issue. If unable to upgrade, using a `Cookie` header in the `headers` parameter is not vulnerable.","severity":{"version":"4.0","score":6.6,"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-10","score":0.0015,"percentile":0.04218,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-346"],"published":"2026-06-02T18:32:50Z","modified":"2026-11-05T05:36:30Z","fixes":[{"ecosystem":"PyPI","package":"aiohttp","fixed_in":["3.14.0"],"sources":["ghsa","osv"]},{"ecosystem":"TuxCare:PyPI","package":"aiohttp","fixed_in":["3.8.6.post6+tuxcare"],"sources":["osv"]},{"ecosystem":"Debian:12","package":"python-aiohttp","fixed_in":["3.8.4-1+deb12u2"],"sources":["osv"]},{"ecosystem":"Debian:14","package":"python-aiohttp","fixed_in":["3.14.0-1"],"sources":["osv"]}],"affected":[{"source":"ghsa","ecosystem":"PyPI","package":"aiohttp","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.14.0"}]}]},{"source":"osv","ecosystem":"Azure
